No team can afford to lose a starting goaltender but, with the way the Flyers have been playing, they especially cannot afford to lose theirs.

The Philadelphia Daily News' Frank Seravalli reports from Flyers practice that goaltender Steve Mason was injured at Flyers practice and needed to be helped off the ice by trainers. The injury appeared significant and NJ.com's Randy Miller reports there was no one around Mason when he went down.

Mason, 26, is 6-10-5 with a 2.49 GAA and a .921 SV% in 22 games (21 starts) this season for the Flyers. His strong play between the pipes is not reflected in his record as he has allowed just one goal in three of his last five starts and no more than three goals in any of those starts. In 90 games for the Flyers since being acquired from Columbus in 2013, Mason is 43-30-12 with a 2.45 GAA and a .920 SV%.

The Flyers are slated to take on the Maple Leafs on Saturday in Toronto.
